Use of ADGS1414D for switching resisters at input of AD7616

Question

I am using AD7616 for data acquisition, I need to acquire 70V and 28V signals as well as 5V analog signals. I am using a resistive dividing network to make my AD7616 channel compatible. Therefor, I need to switch the resisters to configure input range of my acq channels. 
 I couldn't find an application note for this purpose. Any help will be welcome. 
 I am planning to use ADGS1414D for switching . Its a new chip, I am not sure what behavior it will exhibit when hooked up with AD7616. 
 Kind Regards, 
 Asim

Hi Asim, 
 The ADGS1414D is an 8 channel SPST that can operate up to +/-16.5V supply voltages. The switch can pass signals from the VSS to VDD supplies. 
 What voltages are the signals you wish to pass through the switch? 
 As for the switch behaviour, the link below has good information of the different CMOS switch parameters and how they impact a circuit.

Hi Asim, 
 The ADGS5414 would suit better as it can pass 35V signals with a 35V or above VDD supplied to the device.
